All the qualities required to cover the walls of the living room! If your decor is warm and authentic, go for the ocher, straw or saffron shades that will give a Provencal side. For a more contemporary and pop atmosphere, the lemon yellow or buttercup shades will do wonders associated with other tonic colors.
